To aZZ whom it may concern:

''Be it known that I, RAYE. WINCHESTER, a citizen of the United States, residing at.

Vinita, in the county of Craig and, State of Oklahoma, have invented certainnew and useful Improvements in Flushing-Valves, of which the following is a specification;

My: invention relates to what are known 7 as seat-actuated closed-tank closets, being seatis removed.

The invention has for. its object animproved construction andarrangement of the valves which control the admission and dis charge of the water.

.In such closets, as heretofore constructed,

it has not been possible for the manufac turer-to assemble all the parts, because of the necessity for accurately positioning them to properlycooperate with eachflother in.

each individual installation. Moreover,

when so installed, theseats and parts carried thereby are not interchangeable, among different closets. Also, it has been found in practice that, after the valves and seat have been originally assembled and installed, they are thrown out of adjustment by slight wear of the movable parts, so that the valves do not properly close when the seat is depressed into engagement with the top of the bowl. To remedy these defects, I propose to provide means by which the valves can be adjusted relative to the seat actuated device, so that such operating device may be secured to the seat by the manufacturer, and the valves adjusted accord-' ingly when installed. By this arrangement,

. all seats are made interchangeable, and any wear'which occurs may be readily compen sated. 1

In order that my invention may be clearly understood, reference is had to'the accompanying drawing, forming part of this specification, and in which, I V Figure 1 is a central longitudinal section through my improved valve, and associated parts; and, Fig. 2 is an. end elevation of. the valve stem against which the operatmgde: vice bears.

Referring to the drawing in detail, 1 desig- 7 nates a closet bowl, which may be of any suitable type, and 2 indicates the seat. This.

Application filed March 22,1915. Serial No. 15,211;

is hinged at 3 to a suitable bracket inthe usual manner.

Tothe lower s1de of the seat is secured an operating device or arm lfadapted to 'en-- ga-geand actuate the valve stem, as here1nv after'described. Secured in the bowl by means .of alock nut 6 is a fitting 5,'having open ngs 5" through which the flushing .65 thisjfitting 5 is secured'one end of another fittin'gfor valve casing- 7 ,the parts being con- 7 'nected'by a union;9, and having an inter- Water is discharged. .:To the outer, end of posed gasket 8, to insure a tightjoint.

The fitting '7 has formed thereon an inletconnection 10, communicating with theb 'water supply system, and a connection 11, communicating with the pressure tank (not shown) #The'fitti'ng"? is also provided with two. spaced valve-seat's, 12 and 13, facing in opposite'directions,and spaced asshown. Valves 14: and'z15, p'referably formed 0f leather orrubb'er, cooperate with the seats 12 and l3, respectively. Thevalve H is"- carried by avalve stem section16, and the valve15 is carriedby a section'lS, the sec- 'ti'ons 16 and 18 being loosely coupled by means of a pin 16"*, carried byv section 16, entering a socket formed in the end of section 18. The valve 15 is held in position by means of a nut 17 which screws on to a neck 17, carried by the section 18.

The section 18 of the valve'stem is in the form of a hollow sleeve, internally screwthreaded as indicated at 19. Another section 21, in the form of'a rod, isprovided with external threads20 adapted to enter the threaded sleeve, and capable of being adjusted therein to any desired extent. A lock nut 22 is also mounted on the threaded end '20. of the-bar 21, and, when jammed. against the end of the sleeve 18, as shown, serves to hold the parts in their adjusted position. The other endof the rod 21 is screw-threaded to receive a cap 23, preferably hexagonal in shape, which carries a roller '24 adapted to be engaged by the arm or bracket 4, carried by the seat. The cap 23 works through a plug 25, set into the end of the fitting 5, and a packing ring 26, of leather or the like, preferably surrounds the stem 21 to prevent leakage. Nuts 27 are positioned on althreaded portion 28 of the stem 21 to act as a stop to limit the movement of the cap 23, and prevent it from becoming disengaged from the guide opening in the plug 25, as will be obvious,

I Specificationot Letters li'atent. j Patented FbQS, 1916- i A spring 29 bears at one end against a suitable cap 30, and at the other against'the valve ll, and tends to hold the parts in the position shown in the drawings.

' In operation, when the seat is depressed, the arm l, acting against the roller 24, shifts v the whole valve stem to the left, thus opening valve 14: and closing valve 15, permitting water to flow in through connection 10, and

fill the tank. W hen pressure is removed from the tank, the valve stem is moved to the position shown in the drawing, under the influence of the spring 29. This permits the water in the tank to be forced out and thus flush the bowl through the openings 5?.

From the above it will be seen that the armd can be secured on the seat in approximately the correct position by the manufacturer. Then, when installing the fixture, the plumber can adjust'the rod 21 in the sleeve 18 until just the proper length of valve stem has been obtained to cause the valve 15 to close tightly whenthe seat 2 has been depressed into engagementwith the bowl. In;

thesame way, if the parts become loosefrom wear, the sleeve and rod may be readily read usted so as to take up or compensate for such wear, and thus insure the valves always closing properly. By virtue of this construction, also, any seat may betransferred at will from one closet to another, thevalvestem, in .each case, being adjusted to correspond with the location of the arm 4 on that particular seat.

" having inlet and outlet openings, a pair of opposing valve seats formed in said casing, a pair of valves cooperating with said seats to control the flow of water through said openings, and a valve stem carrying said valves, said valve stem comprising two sections, screw-threaded together within said casing, said valve stem lying wholly within said casing with the exception of one end thereof, which end projects a relatively short distance beyond said casing and lies directly in the path of said downwardly extending arm, whereby movement of said arm in one direction forces one of said valves toward its seat, and the other away from its seat, the above described arrangement being such that the length of said valvev stem and the relation between said valves and arm may be adjusted inside of said casing as required to cause the proper seating of said valves. In testimony'whereof I have afliXed my signature in presence of two witnesses;
